The bottle hoisting mechanism, the bottle displacing mechanism, and the bulkhead pick-and-place mechanism are mounted on the frame. The function of the bottle hoisting mechanism is to raise the bottle tops thereon to a predetermined height; the bottle translation mechanism usually has a top of the frame, and the function is to convey the bottle of the top layer of the bottle to the bottle table laterally; A partition is arranged between two adjacent bottles, and after the bottle translation mechanism removes the upper layer of the bottle, the partition pick-and-place mechanism takes out the partition and moves it to the partition collecting frame, and then the bottle lifting mechanism will next The layer of bottles is delivered to the predetermined position, and the bottle translation mechanism continues to remove the next layer of bottles.

The bottle lifting mechanism generally comprises a frame, a lifting fork and a lifting fork lifting driving mechanism capable of driving the lifting lifting, the lifting fork lifting driving mechanism is mounted on the frame, and the lifting lifting drive mechanism comprises a lifting machine and a plurality of chains. The lifting fork is connected to each chain, and the lifting motor drives the lifting fork to lift and lower through the chain. When the lifting lift drive mechanism drives the lift fork to rise, the lift fork drives the bottle top thereon to rise to a predetermined height. However, the operation of the bottle raising mechanism is not smooth enough, and the lifting fork and the bottle above it are liable to sway during the lifting process, so that the bottles collide with each other, causing damage to the bottle.

The bottle lifting mechanism 2 raises the bottle top thereon to a predetermined height; the bottle translation mechanism 3 conveys the bottle of the uppermost layer of the bottle laterally to the bottle table; a separator is disposed between two adjacent bottles in the bottle After the bottle translating mechanism 3 removes the upper layer of the bottle, the partitioning and picking mechanism 4 takes out the partition and moves it to the partition collecting frame, and then the bottle lifting mechanism 2 sends the next layer of the bottle to the predetermined position, and then The bottle translation mechanism 3 continues to remove the next layer of bottles.

(1) Working principle of the bottle lifting mechanism 2:

After the bottle is conveyed onto the lifting fork 22, the lifting motor 26 rotates forward, the left timing pulley 28 is driven to rotate by the first left speed reducer 27, and the first timing pulley 232 is rotated by the first right speed reducer 231, left synchronization The pulley 28 and the right timing pulley 232 respectively drive the lifting fork 22 to rise by the left timing belt 29 and the right timing belt 233 to raise the bottle to a predetermined position; then, each time a layer of the bottle is removed, the lifting fork 22 rises by a certain distance; When all the bottles are removed, the elevator 26 is reversed, the left timing pulley 28 is driven to rotate in the reverse direction by the first left speed reducer 27, and the right timing pulley 232 is driven to rotate in the reverse direction by the first right speed reducer 231, left. The timing pulley 28 and the right timing pulley 232 respectively drive the lifting fork 22 to descend by the left timing belt 29 and the right timing belt 233, and the lifting 22 is restored to the initial position, and after the bottle tray is removed, the next step can be started. Wheel work.

During the lifting process of the lifting fork 22, each of the left lifting guide rollers 224 cooperates with the left vertical rail 23 (the rolling between the left lifting guide roller 224 and the left vertical rail 23), and each right lifting guide roller 226 and right The vertical rails 24 cooperate (the rolling between the right lifting guide rollers 226 and the right vertical rails 24), and the lifting lifts 22 are smoothly raised and lowered along the left vertical width rails 23 and the right vertical rails 24. (2) The principle of the bottle translation mechanism 3:

First, the pinch holder 32 is directly above the lifting fork 22; before the uppermost bottle of the bottle enters the bottle holder 32, the uppermost bottle of the bottle is not in contact with the contact plate 3193, and the contact plate 3193 is at its lowest position, at which time it is close to The switch 3 195 senses the detecting body; when the bottle is raised, the uppermost bottle of the bottle enters the bottle holder 32 and pushes up the contact plate 3 193 upward, the contact plate 3 193 rises and pushes the piston rod of the induction cylinder 3191 and the detecting body rises. When the upper proximity switch 3194 senses the detector, the upper proximity switch 3194 sends a signal to the control circuit, and the control circuit sends a control signal to stop the bottle hoisting mechanism (when the uppermost bottle of the bottle reaches a predetermined height position).

Next, the first gripper assembly position switching mechanism simultaneously switches the positions of the front gripper assembly 324, the left gripper assembly 322, and the right gripper assembly 323 to cause the left gripper assembly 322, the right gripper assembly 323, and the front gripper assembly 324. Simultaneously swinging inward while the second pinch assembly position switching mechanism switches the position of the bottle holder assembly 325, causing the rear pinch bottle assembly 325 to swing inwardly, such that the left pinch bottle assembly 322, the right pinch bottle assembly 323, and the front pinch bottle The assembly 324 and the rear pinch assembly 325 grip the uppermost bottle of the bottle. At this time, the baffle clamp I-seat translation cylinder 3184 drives the baffle holder 3183 and the front baffle 3186 and the baffle clamp 3185 thereon to move backward, and the front baffle 3186 contacts the bottle of the upper layer of the bottle; meanwhile, the bottle The front edge of the partition between the uppermost bottle and the lower bottle is between the upper clamp arm 3 1855 and the lower clamp arm 31852, and the upper clamp drive cylinder 31856 and the lower clamp drive cylinder 31853 drive the upper clamp shaft 31854, respectively. After the lower clamp shaft 31851 is rotated, the upper clamp arm 31855 is engaged with the lower clamp arm 31852 to sandwich the partition plate.

Subsequently, the translation motor 35 drives the left active timing pulley 37 to rotate by the second left speed reducer 36, and drives the right active timing pulley 31 1 to rotate by the second right speed reducer 310, the left active timing pulley 37, the active timing pulley 31 1 drives the pinch holder 32 backward by the left annular timing belt 38 and the right annular timing belt 312, respectively, and pushes the bottle holder 32 and the bottle it grips onto the bottle table. Then, the first pinch assembly position switching mechanism simultaneously switches the positions of the front pinch bottle assembly 324, the left pinch bottle assembly 322, and the right pinch bottle assembly 323, so that the left pinch bottle assembly 322, the right pinch bottle assembly 323, and the front pin holder assembly 324 are simultaneously The swinging outwardly, while the second gripper assembly position switching mechanism switches the position of the gripper assembly 325, causes the rear gripper assembly 325 to swing outward to release the bottle.

Then, the upper clamp drive cylinder 31 856 and the lower clamp drive cylinder 31853 respectively drive the upper clamp shaft 31854 and the lower clamp shaft 31851 to rotate in opposite directions, and the upper clamp arm 31855 and the lower clamp arm 31852 are branched to release the partition; the partition clamp holder The translating cylinder 3 184 drives the baffle holder 3183 and the front baffle 3186 and the baffle clamp 3185 thereon to translate forward. At this time, the uppermost partition of the bottle is taken out by the separator pick-and-place mechanism of the unloading machine and placed in the partition collecting frame.

Then, the translation motor 35 drives the left active timing pulley 37 to reversely rotate by the second left speed reducer 36, and drives the right active timing pulley 31 1 to reversely rotate by the second right speed reducer 310, and the left active timing pulley 37, The right active timing pulley 31 rotates the bottle holder 32 forward by the left annular timing belt 38 and the right annular timing belt 312, respectively, and re-sends the bottle holder 32 directly above the bottle lifting mechanism; jobs.
